as an owner of a Manhattan (and guinea pig) hopefully I can help
Here's what going on. When I started playing with this receiver I ran into a few issues that threw me for a loop. First the HDMI connection did not work. Well it did work for about 5 seconds and after that total.
as noted change the resolution from AUTO to something else. Mine is at 720p through HDMI and no issues
After scanning a satellite I noticed that low FEC tps did not get picked up. I have to put entered in manually.
do you mean low symbol rate? If so that is normal. I dont know why it wont grab symbol rates like 2403 (the knife show on 83W) but can grab the test card on 105W which is at 1000 (the MH actually shows it at 999)
Some FTA channels went dark (on the same Mux). I had a green tint or a bleed out on my screen. I upgraded the receiver with the 3.9 firmware and that seams to clean it a little bit.
sometimes after a scan the channels will log but will show a back screen. I just power off and power back on with the remote and it works fine then
But the one that gets me the most is the Auto Scan. Blind scanning for me is an adventure. It takes over ten minute to fully scan a satellite. I must be doing something wrong but I don't what it is.
how is it setup and what are you scanning?
On KU its usually between 3 and 8 minutes. Some satellites it seems to hang for an unknown reason and 74W was one. But with 74W gone (moved and not being replaced) thats a moot point. While the Coolsat 5000 kicks the MH butt on speed remember the MH has to find both DVB & DVB-S2. If you scan C-Band it will take longer due to more S2 transponders out there.
